The pervasive contamination of industrial, domestic, and agricultural wastewater with nitrate poses profound ecological public health risks. Traditional methods for remediating nitrate-laden water face formidable challenges due to its high solubility stability. However, a promising solution emerges in the form electrochemical reduction (eNO3RR), offering both efficient removal valuable ammonia generation sustainable manner. This review explores burgeoning field eNO3RR, focusing on recent advancements utilizing porous crystalline framework materials − metal–organic frameworks (MOFs) covalent-organic (COFs) as novel class electrocatalysts. These innovative exhibit unique properties such adjustable porosity, diverse structures, tunable pore sizes, well-defined active sites, making them ideal candidates enhancing efficiency selectivity under ambient conditions. By dissecting structure–activity relationship inherent MOF/COF-based electrocatalysts, this aims provide comprehensive understanding their role driving conversion NO3− NH3. Moreover, it identifies current proposes future prospects leveraging these advanced pollutants, glimpse into greener more effective approach remediation resource recovery.

Abstract The electrochemical nitrate reduction for green ammonia production is attracting increasing attention, where the catalysts are widely investigated by controlling compositions or structures to achieve high performance. However, their reconstructions under potentials inevitable and uncontrollable, leading uncertain performance, a confused understanding of mechanism. In this work, strategy proposed pre‐catalyst's reconstruction chemistry toward reaction (e‐NO 3 RR) with superior activity stability. To demonstrate idea, pre‐catalyst fabricated α ‐Co(OH) 2 Cu(OH) ( /Cu(OH) ), which in situ reconstructed tandem catalyst Cu β (Cu/ β‐ Co(OH) ) working potential. Cu/ achieves an optimal Faraday efficiency 97.7% yield rate 3.9 mmol h −1 cm −2 at −0.5 V, outperforming other reported metal‐hydroxide catalysts. experimental theoretical results that catalytic mechanism responsible exceptional performance: 1) functions as donor nitrite; 2) serves active sites generating hydrogen reducing nitrogen‐containing groups. This work highlights controllable improved performance can be realized, provides insightful mechanism, helpful developing stable various applications.

Abstract Electrochemical nitrate reduction reaction (NO 3 − RR) provides a sustainable and efficient way to producing ammonia at ambient condition denitrifying wastewater. However, NO RR is still confronted with some barriers present, because of the sluggish kinetics competitive hydrogen evolution (HER). Particularly, it requires highly robust selective electrocatalysts, which steers complex multistep reactions toward process. Among various Co‐based electrocatalysts demonstrate rapid kinetics, steady catalytic performance, suppressive impact on HER for RR, attracting more attention. In this review, focused Cobalt‐based design corresponding strategies are summarized. detail, these can be concisely classified into five categories, including oxides hydroxides, alloys, metal, heteroatom‐doped materials, metal organic frameworks derivatives. Each category extensively discussed, its concepts ideas clearly conveyed through appropriate illustrations figures. Finally, scientific technological challenges as well promising constructing system in future discussed. It expected that review provide valuable insights guidance rational ultimately advancing their applications industrial scenario high current density, stability, energy efficiency.
